Command History This table includes the following release-specific history entries:
Usage Guidelines Use the traffic-engineering skip form of the command when all IP addresses are unique and MPLS
labels are not mandatory (a non-MPLS/VPN environment).
Use the VPN skip form of the command when all IP addresses are unique, but MPLS labels are used.
Use the VPN auto-learn form of the command in an MPLS/VPN environment where auto-learning is
required due to the existence of private IP addresses and/or VPN based subscribers.
Use the default keyword to set the MPLS configuration to the default value.
CHANGING VPN MODES
VPNs can only exist in either VLAN symmetric classify or MPLS VPN auto-learn, but these two
modes cannot be enabled simultaneously. When changing from one of these VPN-related modes to
another, keep the following guidelines in mind:
• All VPN-based subscribers must be cleared in order to change the tunneling mode. If the connection
with the SM is down, use the no subscriber all with-vpn-mappings CLI command.
• All VPN mappings must also be removed. This can only be done via the SM CLU (which means that
the connection with the SM must be up).
